Tracks

The Track Display sample illustrates how to display 5000 moving tracks received via a web-socket. Density analysis can be applied in a static way on the trajectories or dynamically on the moving tracks.

There are two datasets:

• Tracks : 5000 moving tracks, pushed from a server over a web-socket.
• Routes : the routes each of these tracks is moving over.

You can enable dynamic density , showing density over the moving tracks.
You can also enable static density , showing density over the routes.
